Transcript for California Overflowing With Heavy Rain is Putting People at Risk

to that storm so big it inspires respect everybody as seen from space, it is a monster, a super soaker, about to March east, where winter-weary residents are once again face act lot of snow. ABC's ginger zee in California. Reporter: Almost a nonstop rain. This is Los Angeles river, it has rapids in it, usually it's a trickling stream, close to half-foot of rain in some places. A whole lot more than we is seen since 2011. California, overflowing -- That was a sidewalk -- Reporter: From mud and rockslides to a swift-water rescue along the rushing los Angeles river. Two men and their dogs clinging to this fallen tree. Watch, as they pull one dog then the next into the boat. So much of the rain merely denting the remarkable drought but coming too much too fast for some. We're evacuating, we're getting ready to get everybody out. The mud's coming down, we've got to go. Reporter: At the foothills of San Gabriel mountains at least 1,000 homes evacuating, intermittent mudslides leaving behind trails of debris. Even though a majority of this initial slide came down already, you can see the problem, why the road is closed. This is not road. This is leftover mud, thick throughout the streets. The heaviest rain in almost three years drenching the state with two to six inches already. The winds taking out trees, knocking out power for at least 30,000. Just look at that storm, the center, churning through the pacific -- and it's far from done with California, watch the clock on the top bar. Heavy bands of rain will come in and out for the next 48 hours. Another three to four inches of rain north of Los Angeles, adding to what is already more rain in three days than parts of California has seen in the past year. Now, this same storm is going to rocket east after Sunday and give snow for the great Lakes and northeast. Let me show you how much is expected at least in some of the computer models right now, that pink is six to 12 inches. Some places will get heavier than that. Ginger zee, once again, tracking a storm coast to coast. Thank you, ginger.
